Chris Wesseling of NFL.com set out to find the to post-draft, and identified Christian Ponder as the top candidate (h/t to the Daily Norseman for finding this story):
Christian Ponder, QB, Vikings: The Vikings have brought back Matt Cassel, drafted Teddy Bridgewater as thequarterback of the future and declined Ponder’s 2015 option. So why are they prepared to waste first-team reps on a quarterback who has fallen out of their plans? The logical inference is an attempt to rebuild some semblance of trade value. Ponder still offers higher upside than the average NFL backup. Former offensive coordinator Bill Musgrave is now the Eagles quarterbacks coach. Former quarterbacks coach Craig Johnson is now the Giants running backs coach.
As Wesseling points out, summertime trades are rare but the Vikings are no stranger to late-round summer trades—indeed, A.J. Jefferson was traded after training camp and roster cutdowns, and Minnesota waived former Chicago Bears corner (and current Giants corner) Zack Bowman to do it. With the pick the Vikings traded to the Cardinals (originally acquired from Tennessee for Minnesota’s 2012 7th-round pick), Arizona acquired Carson Palmer form Oakland (sending a 2014 pick as well).
Using that, Oakland traded down with Houston to grab two more picks later in the draft. Houston drafted David Quessenberry and Oakland drafted Mychal Rivera and David Bass.
